Patient leaflet - Maloff Protect 250 mg / 100 mg tablets

1. WHAT MALOFF PROTECT IS AND WHAT IT IS USED FOR

Maloff Protect belongs to a group of medicines called antimalarials. It contains two active ingredients, atovaquone and proguanil hydrochloride.

Maloff Protect is used to prevent malaria. It is available from the pharmacy for adults. It is not suitable for use in children or adolescents unless it has been prescribed for them by a doctor. If you are under 18 and you are visiting an area where there is malaria, talk to your doctor, nurse or pharmacist for advice.

Malaria is spread by the bite of an infected mosquito, which passes the malaria parasite (Plasmodium falciparum) into the bloodstream. Maloff Protect prevents malaria by killing this parasite.

IMPORTANT: You must get advice from a healthcare professional about which antimalarial medicine or medicines to take. You must ask your doctor, nurse or pharmacist if Maloff Protect is suitable for the part of the world that you are visiting. Getting advice for malaria is only one of the aspects to protect your health before your travel. Remember to seek a full travel consultation. If your travel plans change, you must seek updated travel advice.

Protect yourself from malaria

People of any age can get malaria. It is a serious disease, but it is preventable. As well as taking Maloff Protect, it is very important that you also take steps to avoid being bitten by mosquitoes. The bite avoidance measures listed below should be used in combination for maximum effectiveness.

  • Use insect repellent on exposed areas of the skin.
  • Wear clothing that covers most of the

    body, especially after sunset as this is the time when mosquitoes are most active.

  • Sleep in a room with screened windows and doors or under a mosquito net (it is preferable to sleep under a mosquito net treated with insecticide if possible).
  • Close windows and doors at sunset, if they

    are not screened.

  • Sleep in a room with air-conditioning or

    a fan, as mosquitoes are less active in cooler temperatures.

  • Consider using an insecticide (mats, spray,

    plug-ins) to clear a room of insects or to stop mosquitoes from entering the room.

If you need further advice, talk to your doctor or pharmacist.

It is still possible to get malaria after taking the necessary precautions. Some types of malaria infection take a long time to cause symptoms, so the illness may not start until several days, weeks or even months after returning from abroad.

See a doctor immediately if you get these symptoms, particularly within three months but even up to one year after returning home:

  • a high temperature (fever)
  • headache
  • tiredness
  • sweats and chills
  • vomiting

Tell your doctor that you have visited a malaria area.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE MALOFF PROTECT

Do not take Maloff Protect if you:

  • are allergic to atovaquone and/or proguanil

    hydrochloride or any of the ingredients of this medicine (listed in section 6)

  • have kidney disease
  • have liver disease

    Do not take Maloff Protect unless it has been prescribed for you by a doctor or other qualified prescriber if you:

    • are breastfeeding, pregnant or think you may be pregnant (see section ‘Pregnancy and Breastfeeding’)
    • are under 18 years old or weigh less than

      40 kg

    • have ever had epilepsy, convulsions or fits
    • suffer from depression
    • have tuberculosis

Do not take Maloff Protect if you are already taking any of the following medicines:

  • etoposide, used to treat cancer
  • metoclopramide, used to treat nausea and vomiting
  • the antibiotics tetracycline, rifampicin or rifabutin
  • indinavir, efavirenz, zidovudine or certain medicines called protease inhibitors, used to treat human immunodeficiency virus (HIV)
  • warfarin, other coumarin based anticoagulants, or new oral anticoagulants (NOACs) such as dabigatran etexilate, rivaroxaban, and apixaban

Talk to your doctor or pharmacist for advice.

Warnings and precautions:

  • If you are sick (vomit) within one hour of taking your Maloff Protect tablet, take another dose straight away. If you don’t start vomiting until more than one hour after taking Maloff Protect, do not take another Maloff Protect tablet until your next dose is due, as it is likely that Maloff Protect will already be in your system
  • It is very important to take the full course of

    Maloff Protect. If you have to take extra tablets due to sickness, you may need to get some more

  • If you have been vomiting or have diarrhoea, it is especially important to use extra bite prevention, such as repellents and bed nets. The Maloff Protect you have taken may not be as effective because you may absorb less than you need

Tell your doctor or pharmacist if you have taken any medicines to prevent or treat malaria before and they have not worked or if you have had an allergic reaction to them. Maloff Protect may not be suitable for you.

Other medicines and Maloff Protect

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines that you buy without a prescription.

Do not take Maloff Protect if you are taking any of the medicines listed in the above section “Do not take Maloff Protect ”.

REMEMBER to tell your doctor or pharmacist if you start taking any other medicines while you’re taking Maloff Protect.

Maloff Protect with food and drink

Take Maloff Protect with food or a milky drink, where possible. This will increase the amount of Maloff Protect your body can absorb, and make your treatment more effective.

It is best if you swallow the tablets whole and do not crush them.

Pregnancy and breastfeeding

If you are pregnant, think you may be pregnant or intend to get pregnant, or you are breastfeeding, do not take Maloff Protect unless your doctor tells you to.

Pregnant women have an increased risk of developing severe malaria and a higher risk of fatality compared to non-pregnant women.

Seek advice from your doctor or pharmacist if you are pregnant or breastfeeding and need to take an antimalarial.

Driving and using machines

Maloff Protect makes some people feel dizzy. If you feel dizzy, do not drive, use machines or take part in activities where you may put yourself or others at risk.
